GARY - Yes, the mule drive belt will whip or vibrate back & forth... There is a tension spec for the spring loaded idlers.... I think it's in the Operator's manual plus there was a decal on the front face of the mule drive when Your 1450 was new that's probably been removed or painted over.
RUSSELL R. - A 100 should be able to push a fair amount of loose dirt...weights & chains on the rear would really increase the amount... I made a center mounted grader blade for My 72 MANY years ago. I used it to do the finish grading on My Father-in-Law's swimming pool landscaping. It took three of us all day to shovel & wheelbarrow or haul dirt with My cart from 3-4 single axle dumptruck loads (no skid-steer in the family at that time!) but about 15-20 minutes to level the windrows of dirt out and pack it for laying sod. Many ways to get a smooth level surface also.... I've even used an old tire pulled with a chain to smooth a dirt radio controlled race car track before.
